Hi,
I get a warning () using
xyplot. <- function(u) {
BW.theme <-
list(strip.background = list(col = "gray90"),
strip.shingle = list(col=c("gray75")),
layout.heights = list(strip = c(1,1)),
axis.text = list(cex = 0.8),
superpose.symbol=list(col=1, pch=20)
)
xyplot(u[,2]~u[,1],par.settings=BW.theme)
}
U <- matrix(runif(20),ncol=2)
b <- xyplot.(U)
b
and it does not change the color. Further, would such an approach change all
colors (including plot symbols, text, background, etc.)?
But it's funny to see because I played around with par.settings as well. I
tried...
library(lattice)
xyplot. <- function(u) {
xyplot(u[,2]~u[,1],par.settings=list(color=FALSE))
}
U <- matrix(runif(20),ncol=2)
b <- xyplot.(U)
b
... but it didn't work :-(
Cheers,
Marius
